But in mgh2 lewis structure electrons completely donated so no hybrid orbital is necessary. Mgh2 is non polar because ionic in nature. Furthermore, magnesium has a two electrons limit since fluorine is the most electronegative element in the MgF2 molecule. It is so because the Lewis structure is drawn for such molecules where sharing of valence electrons takes place, which is the case with magnesium fluoride. Polar molecules are soluble in water through dipole dipole interactions as water is polar in nature. Hence, the valence electrons present in fluorine is 7 (see below image). The F-Mg-F bond generates a 180-degree angle in the linear geometry. In covalent type of molecules electron cloud can spread to vacant orbital of neighbor atom resulting resonance structure. The electronegative value of a magnesium atom is lower than that of a fluorine atom. For Magnesium (Mg) atom:Valence electrons = 2 (because magnesium is in group 2)Bonding electrons = 4Nonbonding electrons = 0, For Fluorine (F) atom:Valence electron = 7 (because fluorine is in group 17)Bonding electrons = 2Nonbonding electrons = 6. So, it gains one valence electron donated by the magnesium atom to get a -1 charge. According to this idea, the magnesium fluoride molecule must meet the following criteria in order to have a linear structure: The Lewis structure reveals that magnesium fluoride (MgF2) has a linear molecular geometry. Mgh2 is non polar as there is no any covalent bond in the molecule. Place the valence electrons in the Mg-F bond pairs starting with the core magnesium and two fluorine atoms in the MgF2 molecule.
